e1c9739577 Remove the flags argument handling in fchmodat syscall

function in libc already, so Occlum does not need to accept this argument.

f1e5f574ca Add support for DCAP 
1. Five new ioctl commands of /dev/sgx are added for occlum
applications to securely get and verify DCAP quote;
2. Not all the functions of the intel DCAP package are open to
developers to simplify the DCAP usage;
3. The test may only run on the platform with DCAP driver installed;
4. A macro OCCLUM_DISABLE_DCAP is used to separate the DCAP code from
the other code.
5. Skip DCAP test when DCAP driver is not detected or in simulation mode

9809d81c4e Fix a bug of channels 
This bugfix ensures that when an object of Producer/Consumer for
channels is dropped, its shutdown method is called automatically. This ensures
that the peer of a Producer/Consumer gets notified and won't wait indefinitely.
